Description
Die Erfindung betrifft eine Bürstendichtung zum Abdichten relativ zueinander beweglicher Bauteile, mit einem Dichtungsteil, dessen mit ihren freien Enden zur Dichtfläche ausgerichteten von einem Borstenrücken gehaltenen Borsten von einer Stützplatte in ihrer vorbestimmten Arbeitslage gehalten sind.The invention relates to a brush seal for sealing relatively movable components, with a sealing part, which are held with their free ends aligned with the sealing surface held by a bristle back bristles of a support plate in its predetermined working position.
Bei bekannten Bürstendichtungen dieser Art ist das die Borsten tragende Dichtungsteil in einem eine Deck- und eine Stützplatte aufweisenden rotationssymmetrischen Borstengehäuse derart eingespannt, dass die freien Enden der Borsten radial nach innen gegen die abzudichtende Fläche gerichtet sind; vgl.
Solche zum Abdichten eines Rotors gegen einen Stator dienende Bürstendichtungen, deren Deck- und Stützplatten miteinander verschweißt oder durch andere Fügeverfahren (z.B. Bördeln) miteinander verbunden sind und die zudem einen falschen Einbau sowie ein Verdrehen der Bürstendichtung verhindernde Positionierungsmittel am Borstengehäuse aufweisen müssen, denen entsprechende Positionierungsmittel an einer Anlagefläche des die Bürstendichtung tragenden Bauteils zugeordnet sind, weisen einen aufwendigen Aufbau auf und sind nur zum Abdichten rotationssymmetrischer Körper geeignet.Such for sealing a rotor against a stator serving brush seals whose cover and support plates are welded together or connected by other joining methods (eg crimping) and also must have a wrong installation and a rotation of the brush seal preventing positioning on the bristle housing, where appropriate positioning are assigned to a contact surface of the brush seal component carrying, have a complex structure and are only suitable for sealing rotationally symmetrical body.
Der Erfindung liegt die Aufgabe zugrunde, den Anwendungsbereich solcher Bürstendichtungen zu erweitern, deren Aufbau zu vereinfachen und derart weiterzubilden, dass diese zum Abdichten beliebig also auch räumlich gekrümmter Dichtflächen geeignet sind.The invention has for its object to extend the scope of such brush seals, simplify their structure and further develop such that they are suitable for sealing any so also spatially curved sealing surfaces.
Ausgehend von einer Bürstendichtung der eingangs genannten Art ist diese Aufgabe erfindungsgemäß dadurch gelöst, dass die Stützplatte als selbständiges Klemmglied für das durch Einpressung in einer eine Anlagefläche für das Stützglied aufweisenden Ausnehmung des die Bürstendichtung tragenden Bauteils gehaltenen Dichtungsteil ausgebildet ist.Based on a brush seal of the type mentioned above, this object is achieved in that the support plate is formed as an independent clamping member held by press-fitting in a bearing surface for the support member having recess of the brush seal member bearing seal member.
Die erfindungsgemäß Ausbildung umfasst lediglich ein Dichtungsteil und die die Borsten des Dichtungsteils in ihrer vorbestimmten Arbeitslage haltende als Klemmteil für das Dichtungsteil ausgebildete Stützplatte, die in beliebig gekrümmten Ausnehmungen in Form von Nuten des die Bürstendichtung tragenden Bauteils einpressbar ist und dabei eine kraft- und formschlüssige Befestigung für das Dichtungsteil bildet. Damit erübrigen sich der Aufbau des bisher üblichen verschweißten oder gebördelten Borstengehäuses und die Ausbildung von besonderen Positionierungsmitteln.The inventive construction comprises only a sealing member and the holding the bristles of the sealing member in its predetermined working position formed as a clamping part for the sealing part support plate which can be pressed into any curved recesses in the form of grooves of the brush seal component and thereby a non-positive and positive fastening forms for the sealing part. This eliminates the structure of the previously customary welded or beaded bristle housing and the formation of special positioning means.
Für einen eventuell notwendigen Austausch des Dichtungsteils ist die Stützplatte aus der Nut zu entfernen. Für das Einsetzen eines neuen Dichtungsteils wird eine neue Stützplatte benötigt, da die bisherige Stützplatte beim Entfernen aus der Nut unbrauchbar wird.For any necessary replacement of the sealing part, the support plate is to be removed from the groove. For the insertion of a new sealing part, a new support plate is needed because the previous support plate is unusable when removed from the groove.
Durch diese verblüffend einfache Ausbildung der durch Einpressung gehaltenen Teile der Bürstendichtung wird eine leichte und kostengünstige Montage und Demontage auch bei komplizierten Anwendungsfällen, die beliebig gekrümmte Dichtflächen umfassen, erreicht, was mit den bisher bekannten Bürstendichtungen nicht möglich war.This amazingly simple design of the press-fitted parts of the brush seal a lightweight and inexpensive assembly and disassembly even in complicated applications, which include arbitrarily curved sealing surfaces achieved, which was not possible with the previously known brush seals.
Nach einem bevorzugten Ausführungsbeispiel der Erfindung weist das als Stützplatte ausgebildete Klemmglied eine in den Bereich der Ausnehmung reichende den Borstenrücken des Dichtelements in der Ausnehmung klemmende Rändelung sowie eine mit der Anlagefläche der Ausnehmung korrespondierende Anlagefläche auf.According to a preferred embodiment of the invention, the clamping member designed as a support plate has a reaching into the region of the recess of the bristle back of the sealing element in the recess clamping knurling and a corresponding with the contact surface of the recess contact surface.
Nach einem weiteren Merkmal der Erfindung weist das als Stützplatte dienende Klemmglied eine mit der Anlagefläche der Ausnehmung korrespondierende Anlagefläche sowie in den Bereich der Ausnehmung reichende wechselseitige wellenförmige Vorsprünge auf, die einerseits in eine Hinterschnittfläche der Ausnehmung greifen und andererseits am Borstenrücken des Dichtungsgliedes anliegen.According to a further feature of the invention, serving as a support plate clamping member has a bearing surface of the recess corresponding contact surface and in the region of the recess reaching mutual undulating projections on the one hand engage in an undercut surface of the recess and on the other hand abut the bristle back of the sealing member.
Auch kann erfindungsgemäß das als Stützplatte dienende Klemmglied einen den Borstenrücken des Dichtungsgliedes teilweise umfassenden in die Ausnehmung des die Bürstendichtung tragenden Bauteils ragenden Bund aufweisen, dem eine der Anlagefläche gegenüberliegende Hinterschneidung in der Ausnehmung zugeordnet ist, während mittels einer Bördellippe des Bundes der Borstenrücken des Dichtungselementes zumindest teilweise umfasst ist.Also, according to the invention serving as a support plate clamping member have a bristle back of the sealing member partially comprehensive in the recess of the brush seal supporting member projecting collar, which is associated with a contact surface opposite undercut in the recess, while at least by means of a flange of the federal government of the bristle back of the sealing element is partially included.
